LANTERN.

SPECIFICATION forming part of Letters Patent No. 259,455, dated June 13,1882.

Application filed March 9, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, CHAR-LES FIELD AN- DERSON, of Bay City, in thecounty of Bay and State of Michigan, have invented a new andusefulImprovementin Lanterns,of which the following is a full, clear,and exact description.

Myinvention relates to a lantern which may be readily attached to thecollar of an ordinary lamp.

The invention consists in a novel construction of a lantern body orframe provided with a bisected bottom operated by a bail which passesthrough the top of the frame at diagonally-opposite corners and throughbraces at the bottom of the frame, and is then secured to the bisectedbottom, and other devices, combined, arranged, and operating ashereinafter more particularly described. A a

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective view of my invention, showing the dividedbottom opened to receive a lamp-collar. Fig. 2 is a vertical sectionalview, showing the bottom closed; and Fig. 3 is a view of the under sideof the bisected-bottom.

A is a lantern-frame, through the top of which passes a bail, B, eachend of which is secured to one of the sections of the divided bottom 0.The said frame or body A has triangular braces to at its lower corners,and lugs to between said corners for securing the lower edges of theglass sides. Through two of the corner-braces a, at diagonally-oppositecorners, passes the said bail. The bottom 0 is composed of two sectionsof triangular form and provided with revolving plates 0, said plateshaving semicircular notches c 0", of different sizes, provided with rimsc 0 for the purpose of clamping difi'erent-sized lamp-collars. Thebottom D of the lantern-frame Ais beveled or tapered to enable theturned-up edges 6 of the bisected bottom (3 to slip over it easily whenit is drawn up by the bail. The bail B is bentinward and then outward atthe of the lantern-frame, so as to act as springs and separate the twosections of the bottom 0 when the bail is pushed down.

Around the upper part of the lantern-frame, on the inner side, is astrip of wire netting, E, which allows of the escape of the smoke andgases when the lantern is in use. Behind this netting are springs Gr,formed by bending a piece of wire at a right angle midway of its length,with a coil, g, at the angle. One arm or branch of each of these springsis secured to the top of the lantern-body, and the other arm extendsdownward parallel with the inner surface of the netting E. The glasssides of the lantern are placed in position by inserting their upperedges between the springs G and the netting E, and then lowering themuntil their lower edges rest on the lower portion of the frame A and areheld in place by the lugs a The top of the lantern is provided with aknob, H, to facilitate the operation of attaching and detaching thelantern to and from a lamp, which is as follows: The knob His held.

with one hand,while the bail B is pushed down with the other until theportions marked I) reach the corner-braces a. This separates thesections of the bottom 0 to the position shown in Fig. 1, so that theymay be placed over and around the collar of an ordinary lamp either withor without its chimney. Then by drawing up the ball the notches c or cand rim 0 or clamp the collar of the lamp firmly be tween them, so thatthe lamp may be carried by the lantern.

The advantages of my invention are: The lantern can be readily appliedto anyordinary lamp, either with or without a chimney, and by turningthe plates 0 by means of the rings h the notches c or 0 may be adjustedto fit collars of different sizes. The plates 0 are pressed closelyagainst the bottom 0 by the about midway of their length, so that theends 5 of said springs bearing against the plates hold them in place ineither position.

Having thus fully described myinvention, 1 claim as new and desire tosecure by Letters Patent-=- 1. A lantern frame or body provided with abisected bottom attached to and operated by a bail passing throughguide-braces at thebottom of said frame, so as to separate said bisectedbottom to allow it to grasp the collar of a lamp, substantially asherein described.

2. The combination, with the frame A, provided with the corner-braces a,of the bail B, bent as shown at b b, and the bisected bottom 0, attachedto and operated by said bail, substantially as and for the purposesherein described.

3. The combination, with the bisected bottom 0, constructed asdescribed, of the revolving plates 0, provided with notches c c and rims0 0 substantially as herein described.

4. The combination, with the bottom 0 and l holding the glass sides inplace, substantially as shown and described.
